magnetization module and the other is the signal acquisition module. The principle
block diagram of the MAE detection system is shown in Fig. 16.2.
The excitation magnetization module is used to generate an alternating magnetic
field, which enables the magnetization process of the test piece to be detected, thereby
exciting the elastic wave pulse. The signal acquisition module is used to receive
and process signals, and amplify the signals for subsequent research. In this test
